摘要
为了准确评价江淮地区地热水可开采资源量及随地热水开采的温度变化,根据研究区地质、水文地质及地热地质特征概化出了地热水系统的概念模型,并构建了相应的地热水非稳定渗流与热量运移三维耦合数值模型,模拟预测了地热水水位降深条件为50m时各地热水井地热水的可开采资源量及温度的变化趋势。结果表明:江淮地区6口地热水井年地下水可开采资源量达51 290 m^(3),各地热水井随地热水开采的温度变化均不超过1℃。
In order to accurately evaluate the recoverable amount of geothermal water and the temperature variation of geothermal water exploitation in Jianghuai region,a conceptual model of geothermal water system was generalized according to the geological,hydrogeological and geothermal geological characteristics of the study area,and a corresponding THREE-DIMENSIONAL coupled numerical model of geothermal water unsteady seepage and heat transport was constructed.The variation trend of recoverable geothermal water resources and temperature in geothermal water wells is predicted when the water level of geothermal water is 50 m.The results show that the annual recoverable groundwater resources of the six geothermal wells are up to 51 290 m^(3) in the Jianghuai Region,and the temperature variation of the geothermal wells everywhere does not exceed 1℃.
